a male XLR connecter trick.

Given the dummy mic, the microphones, the interface, and
the Jethead which will arrive on Wednesday, how would you
go about deciding whether the Jethead is going to be able
to deliver clean enough gain that it surpasses and improves
my existing preamps.Â*Â* I know I could just listen, but it's
tough to pick out the noise in my residential bedroom from
machine noise.

How would we do this in science class?

You'll probably also need an audio oscillator. It can be a cheap one
-- even the Shure Oscillator in a plug will work (do they still make
that?)

Smartphone app maybe !

I have Signal Suite Pro on an iPod Touch (g4) - maybe one and only Apple
product.Â* But many reasonably sophisticated sig-gen apps available now
for free on Android.

Ooops - for 'maybe' read 'my'.
